UNITED STAT S PATENT GFFIGEQ THOMAS HIBBERT, OF OOGHRAN, INDIANA.

RAILWAY CONTINUOUS DRAW-BAR.

SPECIFICATION forming part of Letters Patent No. 230,549, dated July 27,1880.

Application filed June 12, 1880.

To all whom it may concern Be it known that I, THOMAS HIBBERT, ofCochran, in the county of Dear-born and State of Indiana, have inventeda new and valuable Improvement in Continuous Draw- Bars for Oar-Bumpers;and I do hereby declare that the following is a full, clear, and exactdescrip tion of the construction and operation of thesame,reference'being had to the annexed drawings, making a part of thisspecification, and to the letters and figures of reference markedthereon.

Figure 1 of the drawings is a representation of a bottom view of myimproved drawbar. Fig. 2 is a side view of the same, and Figs. 3 and 4are respectively bottom and side views of a modification thereof.

This invention has relation to improvements in that class of draw-barswherein the coupling-boxes are connected together by longitudinal rodsextending under the bottom of the car.

The nature of the invention w be hereinafter more fully set forth.

In the accompanying drawings, the letter A designates the frame-work ofthe bottom of a car, having at its middle portion the parallel beams aa, to the under sides ofwhich are secured the parallel wooden beams b,that support the rabbeted ends cof the draw-head B. In the ends of beamsb, which terminate short of the end of the car-frame, are formedrecesses c, projecting out centrally from which are pins d, around whichare arranged the coil-springs e. The outer ends of the pins 01 aresupported-by metallic brackets f, secured to beams b and to the beams toa. of the carframe, and the said pins serve as guides to a follower, g,which bears upon the ends of the springs, and which is traversed by therabbeted end 0 of the draw-head B, as shown.

The front portion of this draw-head is supported by a stirrup, K, in theusual manner, and it has free endwise motion through the same.

The draw-head G at the other end of the car, and its appliances, areprecisely the same in construction as draw-head B andits connections.

' The draw-heads B 0, between the stirrups (No model.)

and brackets f, are provided with a transverse horizontal slot, i, ofoblong form, in each of which is seated a metallic key, l, projectingequally from both sides, the ends of which are connected by thelongitudinal draw-rods D. The ends-of these rods are provided withoblong slots i, which are passed over the pro? jectin g ends of thesekeys and secured thereon by means of pins j extending through said keys.

When the draft is applied by the engine the strain thereof istransferred to the rear end of each car of the train, thus relieving itsframe of all stress lengthwise, owing to the yielding of thebuffer-springs at the rear end of the car and the abutting of thefollower thereat against the extremities of the buffer beams or blockscaused by the draw-rods D.

In backing the draw-heads are pressed inward, the followers pressedagainst the ends of the blocks 12, and the springs e pressed back intotheir recesses, when they are relieved of further compression,whichwould result in'injury to their resilient qualities.

In backing the train the inward movement of the draw-heads B 0 occurswithout bending the rods D, owing to the engagement of the keys l in thelongitudinal slots of the ends of the said rods.

Should the rods break the draw-heads are prevented from pulling out ofthe frame of the car by means of a key, 112, extending through therabbet of the said heads behind the folarranged between them in a recessformed about midway of their length.

The rabbeted end of the draw-bar extends through the spring and itsrecess, and bears with its shoulder a against the outer end of theformer, and the transverse key extends through longitudinal horizontalslots 0 in the blocks 1). This modification is clearly illustrated inFigs. 3 and 4.

What I claim asnew, and desire to secure by Letters Patent, is-- l I Thecombination, with the car-frame having the parallel buffer-blocks b,springs a, recessed into the ends of said blocks, the guide-pins d,

In testimony that I clairn the above I have 10 hereunto subscribed myname in the presence THOMAS HIBBERT.
